Old enough to be a grandfather. Not sure what age has to do with this genre which seems to span all age groups, though.
Just started to seek out Jazz about 3 weeks ago. Local radio show has jazz brunch on Sundays. Very listenable. I've now listened to Art Blakely, Dave Burbeck, Ella Fitzgerald, Miles Davis, Diana Krall, Cannonball Adderly, Arutruo Sandoval, Bela Fleck and the Flecktones, and Chick Corea. Love them all and so happy I've found this genre.
